# CMakeDependentOption
|
|
# --------------------
|
|
#
|
|
# Macro to provide an option dependent on other options.
|
|
#
|
|
# This macro presents an option to the user only if a set of other
|
|
# conditions are true. When the option is not presented a default value
|
|
# is used, but any value set by the user is preserved for when the
|
|
# option is presented again. Example invocation:
|
|
#
|
|
# ::
|
|
#
|
|
# CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
|
|
# "USE_BAR;NOT USE_ZOT" OFF)
|
|
#
|
|
# If USE_BAR is true and USE_ZOT is false, this provides an option
|
|
# called USE_FOO that defaults to ON. Otherwise, it sets USE_FOO to
|
|
# OFF. If the status of USE_BAR or USE_ZOT ever changes, any value for
|
|
# the USE_FOO option is saved so that when the option is re-enabled it
|
|
# retains its old value.
